Bubbles will be named if they appear, lol, like rare, about damn time, and wtf. I tried squeezing hoses (while capped) with no luck. Gonna wait until it cools off later tonight and pull tstat and check it's activity in boiling water.
Could losing to much coolant during the re-orrientation of tstat leave it unable to open as the air may be holding the coolant back (wild guess)from getting to it?
